How long does it take to walk threw a wall?

The time it takes to run therough a wall depends on 2 things:

First, how many times you run into the wall and second, how hard you run into the wall. Depending on the amount of each of these criteria the outcome will either be you making it through the wall or knocking yourself out after impact.

You can't do it safely unless the wall is fabricated in such a way as to make it possible for a person to walk though it without injuring themselves. People in movies and characters in Cartoons might walk through walls or through glass, but it isn't real. Don't try it yourself.
